mg/dL to mmol/L formula

The formula to convert milligrams per deciliter (mg/dL) to millimoles per liter (mmol/L) is:

mmol/L = mg/dL / Conversion factor

  • mg/dL = milligrams per deciliter
  • mmol/L = millimoles per liter
  • CF = Conversion Factor

Formula for glucose mg/dl to mmol/l = milligrams per deciliter / 18

Here are some common conversion factors for a few substances:

Conversion factor – The conversion factor is the molecular weight of the substance divided by 10. = MW / 10

How to Calculate mg/dL to mmol/L?

Here’s a step-by-step guide on how to calculate the conversion:

Step 1: Identify the molecular weight of the substance you are converting- for example molecular weight glucose = 180g/mol.

Step 2: Divide the molecular weight by 10 to get the conversion factor: Conversion factor for Glucose = 180 / 10 = 18

Step 3: Take the concentration value in milligrams per deciliter

Step 4: Apply the formula to calculate the concentration in mmol/L:

Concentration in mmol/L = mg/dL / 18

Example of mg/dL to mmol/L

Example – A glucose concentration of 126 mg/dL. then convert into mmol/L.

Step 1: Molecular Weight (glucose) = 180g/mol
Step 2: Conversion factor = MW/10 = 180 g/mol / 10 = 18

Step 3: glucose concentration (mg/dL) = 126 mg/dL

Step 4: Concentration in mmol/L = 126 mg/dL / 18 = 7 mmol/L

So, a glucose concentration of 126 mg/dL is approximately equal to 7 mmol/L.
